What Do You Need To Know To Choose The Right Cable Terminations And Joints?

Devices for cable terminations and joints production is extra innovative than ever before, as users are becoming a growing number of curious about the new technical advantages that these machines offer. Both brand names and also makers are transforming their interest to high-productivity, low-consumption equipment that fulfills the highest possible ecological and also discharge requirements and, on top of that, uses options for recycling used heat /cold shrink cable termination and joint with increasing yields. In this context, cable terminations and jonts combining plant manufacturers and also brands are establishing new technological solutions to fulfill the demands of customers around the globe, each geographical as well as climatic location having their own operating problems.

What Is Cable Termination And Joint Production？

The cable termination and joint is generally made of cold shrink tube or heat shrink tube. Cable termination below 10kv are relatively simple, mainly including terminal connection, heat-shrink or cold-shrinkable tube installation, grounding and shielding treatment, etc. Generally bought cable terminations have installation instructions. Above 110kv is much more complicated and must be installed by a special installation company or manufacturer.

Product Categories

1. According to installation materials, it can be divided into heat shrinkable cable termination and joint and cold shrinkable cable termination and joint.

2. According to the working voltage, it is divided into 1KV cable joint, 10KV cable joint, 27.5KV cable joint, 35KV cable joint, 66KV cable joint, 110KV cable joint, 138KV cable joint and 220KV cable joint.

3. According to the use conditions, it is divided into indoor cable terminal head and outdoor cable terminal joint.

4. According to the number of cores, it is divided into single-core end joint, two-core end joint, three-core end joint, four-core end joint (divided into four cores and 3+1), five-core wiring connector (divided into five cores, 3+2 and 4+1).

 

Features of Heat Shrink Cable Termination Joints and Cold Shrink Cable Termination Joints

Heat shrinkable cable termination and joint is widely used in the terminal of XLL or oil-immersed cable of 35kV and below voltage class. Compared with the traditional cable accessories, it has the characteristics of small size, light weight, safe and reliable, convenient installation and so on. The product conforms to GB11033 standard, the long-term use temperature range is -55℃ ~ 105℃, the aging life is up to 20 years, the radial shrinkage rate ≥50%, the longitudinal shrinkage rate <5%, the shrinkage temperature is 110℃ ~ 140℃.

Cold shrinkable cable termination and joint is made of elastomer material (commonly used silicone rubber and ethylene propylene rubber) in the factory injection vulcanization, and then expansion lined plastic screw support, forming a variety of cable accessories. Cold shrinkage stress control tubes are now commonly used, with voltage grades ranging from 10kV to 35kV. Cold shrinkable cable terminal joint, 1kV class using cold shrinkable insulation tube to strengthen insulation, 10kV class using cold shrinkable joint inner and outer semi-conductive shielding layer. Cold-shrinkable branch bushing is used at the bifurcation of the three-core cable terminal. Cold shrinkable cable terminal has the advantages of small volume, convenient and quick operation, no need for special tools, wide application range, fewer product specifications and so on.

In contrast to heat-shrinkable cable accessories, there is no need for fire heating, and after installation, moving or bending will not cause disconnection between the inner layers of the accessories as with heat-shrinkable cable accessories (because the cold shrinkable cable terminal joint is the tightness of elastic compression). Compared with the prefabricated cable accessories, although the elastic compression force is relied on to ensure the internal interface characteristics, it does not correspond to the cable section one-to-one like the prefabricated cable accessories, so there are many specifications.

Choosing the Right Cable Termination Assembly

Likewise, there is always a possibility to locate a factory. There is always an opportunity to discover an currently made use of one that might fit perfectly with your needs as well as budget Still. Bear in mind that if you purchase from someone aside from brand names or manufacturers a used cable termination and joint mixing plant. On the short term, save loan yet on the long term, it can become a costly problem.

Things to consider before choosing to buy an cable termination Combining Plant.

Take into consideration if what you need is cold shrink termination kits or heat shrink termination kits.

Look for brand names as well as suppliers that provide support as well as assistance in selecting the most effective system.
